Credentials consist of an account domain, user name, and password that are used to process procedures. By default, Microsoft Provisioning Framework (MPF) uses MPFServiceAcct credentials if you do not have impersonation enabled, or the caller's credentials, if you do have impersonation enabled. Using Provisioning Manager, you can specify credentials for one or more accounts that can process specific procedures. Use the Execute as property of each procedure to invoke the appropriate credentials.
For more information on MPF credentials, see Administering credentials in Provisioning Manager Help.
After you have set up MPF, administration should be minimal.
